original 20R-8060 C7 C9 Engine Diesel Fuel Injector Fit 330D 336D E336D Excavator 387-9438 245-3516 new injector original new injector

Specifically engineered for the C9 engine family, this fuel injector delivers precise fuel metering and consistent spray patterns essential for the high-pressure common rail system found in C9, C9 ACERT, and C9.3 power units. The injector assembly is manufactured to OEM dimensional and performance standards, with precision-ground control valves, high-strength alloy steel internal components, and advanced machining tolerances that ensure reliable operation within the demanding combustion parameters of C9 series engines. The electronically controlled solenoid enables accurate injection timing and volume control, supporting improved combustion efficiency, faster throttle response, and lower fuel consumption across a wide range of operating conditions.

Designed as a direct-fit replacement for the authorized OE reference 20R-8060, this injector matches the original equipment specifications required by C9 ACERT and C9.3 diesel platforms. It is widely deployed in construction machinery such as 330D, 325D, and 336D excavators, 950H and 966H wheel loaders, articulated dump trucks, and motor graders, as well as in generator sets, marine propulsion engines, agricultural equipment, and heavy-duty power generation systems. Each injector is built to withstand the elevated rail pressures, vibration loads, and thermal cycling associated with industrial and off-highway duty cycles, providing reduced exhaust emissions, quieter engine operation, and improved cold-start performance.

Prior to installation, technicians should verify the injector part number against the engine serial number, inspect the fuel rail for contamination, replace all injector seals and copper washers, examine the injector harness and electrical connectors, assess fuel quality, and check the cylinder head injector bore condition. When these pre-installation procedures are followed and proper maintenance practices are observed, the injector typically delivers a service life of 8,000 to 15,000 operating hours, ensuring long-term reliability and consistent performance for C9 powered equipment across construction, mining, marine, agricultural, and stationary power applications.
